SEMINAR: Accidental matter at the LHC


April 28 2015, 12:00pm - Seminar room

Speaker: Luca Di Luzio (U Genova)

Abstract : In this talk I will discuss a class of weak-scale extensions of the Standard Model which automatically preserve its accidental and approximate symmetry structure at the renormalizable level and which are hence invisible to low-energy indirect probes.

By requiring the consistency of the effective field theory up to scales of 10^15 GeV and after applying cosmological constraints, we arrive at a finite set of possibilities. One of the most striking signatures of this framework is the presence of new charged and/or colored states which can be efficiently produced in high-energy particle colliders and which are stable on the scale of detectors.
